Pros

Being a Berkshire Hathaway subsidiary provides financial stability in otherwise volatile economic environments. Berkshire also provides employees access to steep discount programs. Excellent benefits, including Medical (Anthem BCBS/Kaiser), Dental, Vision, FSA/HSA, short-term and long-term disability, critical illness, supplemental life, etc. Very low deductibles and out-of-pocket maxes. The employer pays the total cost of parking or an RTD pass. 3% 401k match upfront. Annual Variable Incentive Plan (VIP) with annual raises and up to an additional 4% 401k match dependent on meeting plan. Annual PTO bank with new employees receiving 15 days + 4 floating holidays + 7 Federal holidays. Unlimited sick leave. Corporate employees work a flexible schedule with 2 days remote and 3 days in the office per week. Ample opportunities for training, continuing education, and professional development. Tuition assistance is available. Mobility available within the company to transfer internally to other positions. Strong Senior Leadership team. Significant focus on volunteerism, community-building, and supporting local non-profit partners.

Cons

Very traditional, conservative corporate culture has led to significant turnover, but senior leadership is aware and working to make changes for the better, including implementing flexible schedules. Company culture varies from team to team - employee satisfaction seems to vary based on the strength of middle management. Historically lacking in Diversity and Inclusion (DI) efforts, but senior leadership is aware of this as well. The company is taking significant action internally to improve DI within the company.

Huge Red Flags

Pros

An income, and some of the coworkers were friendly.

Cons

Management couldn't or wouldn't train new hires, at all. We had few training sessions disbursed randomly throughout a 2 month period, and other than that, all their "training" was, was shadowing their other employees all day every day. Almost none of which had been there for more than 6 months. Other than that I sat at my desk with no direction and nothing to do unless I was literally *constantly* asking the manager for anything to do to keep me busy and actually do something. If not, they just acted like you weren't even there. It was extremely corporate in the worst ways, and they told us they didn't "trust" their employees enough to let them work remotely. Extremely environmentally irresponsible and force you to print out and keep papers for years instead of choosing a different option so they could go paperless like most businesses in the 21st century. They invested nothing into my professional progress and development while there, or into the training needed for ANY new hires. Not surprised at all that their turnover rate is through the roof, but they can't seem to understand it.

Pros

Located in a fairly decent part of northern Ohio.

Cons

Upper management is honestly a joke. I was there less than 1 year and answered to 3 different plant managers. So, tons of dysfunctionality... Instead of updating equipment for safety and longevity, this place spends money on painting walls while the steel around the frame corrodes away. There are two kinds of business, "how much will it cost" and "how much will we make"? This place is all about cost... Truly a scary place to work, hence the reason I left in less than a year. Since my employment, I've learned 3 newer hire engineers also quit before their year was up as well. This place has some serious problems.
